Abstract: There is variety of products of different brands available in the market for the customer of different levels which can satisfy their specific demands. The customer has been offered by means of variety of products of the same species and category with different features and attribute. This enhance the competition between the brands, resultantly make efforts to stimulate the customers towards their products by means of different policies, which sometimes can make customer confuse between the brands and their products to – what to pick and what not to. In this research paper we have taken nine laptops of different brands of nearly same range of specifications and Multi Criteria Decision Making (MCDM) Methods are applied to choose the best option among the different alternatives. Entropy method is used to evaluate the weight of the feature attributes.

Assessment of risks is a key task in the project management. In this process, Risk Breakdown Structure (RBS) approach can be utilized to identify project relevant risks. In the previous classical method, only Limited number of attributes is considered in the evaluation that can cause unreliable results. In this paper, an attempt has been made to introduce and involve a relatively comprehensive set of attributes for applying in Multi Attribute Decision Making (MADM) techniques. Using this model, the risks of tunneling construction in the Seimareh dam project, located in South-West of Iran, are assessed and ranked. For the collection of experts' judgments, group decision making method by conducting various decision panels was applied. Also for the risk ranking, Linear Assignment (LA), Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) and Simple Additive Weighted (SAW) methods were considered. Final ranking of the risks was computed using integration methods. It was concluded that the risks economical factors and guarantee are the project most and least critical risks, respectively.

1.ABSTRACT Due to the high thermal efficiency and obvious energy-saving effect, supercritical generating units are widely used in thermal power generation. High temperature and high pressure are needed for water to reach the supercritical state. Boiler or steam pipe of the supercritical generating units to withstand high temperature and high pressure. Because of P91 and P92 materials have excellent mechanical properties at high temperature, so these materials are widely used in boilers or steam pipes fabrication. P92 steel is created based on P91, which has better high-temperature strength and creep performance than P91. This study evaluated and compared steel P91 and P92 mechanical properties for SAW welds.

Pemilihan pegawai terbaik merupakan salah satu aspek yang cukup penting di perusahaan karena dengan sumber daya manusia yang unggul dan memiliki kompetensi tinggi dapat meningkatkan produktivitas dan kinerja suatu perusahaan serta menghasilkan pemimpin-pemimpin hebat di masa depan. Beberapa permasalahan yang terjadi pada pemilihan pegawai terbaik di PT BPD Jawa Barat & Banten, Tbk (Call Name : bank bjb) antara lain yaitu pengolahan data kandidat pegawai terbaik yang akan diseleksi masih membutuhkan waktu yang lama karena belum memiliki standar dan masih memakai sistem manual sehingga proses penilaian masih belum transparan, akurat dan terpercaya. Penentuan pegawai terbaik di bank bjb sangat memerlukan sistem pendukung keputusan sebagai rekomendasi kepada Direksi. Sistem pendukung keputusan penentuan pegawai terbaik yang dilakukan pada penelitian ini menggunakan tiga metode yaitu Simple Additive Weighting (SAW), Analytical Hierarchy Process (AHP), dan Technique For Order Preference By Similarity To Ideal Solution (TOPSIS). Penelitian akan menghasilkan sebuah sistem pendukung keputusan yang dapat merekomendasikan pegawai terbaik pada bank bjb berdasarkan kriteria yang telah ditetapkan yaitu nilai kinerja individu, nilai kinerja unit kerja, kehadiran, perilaku, pencapaian target kerja, masa kerja, pendidikan, penilaian makalah, presentasi, dan hasil wawancara.

Spor endüstrisi, spor kulüpleri, taraftarlar, sporseverler, yayıncı kuruluşlar, finansal yatırımcılar gibi paydaşların yer aldığı küresel ölçekli bir yapıya sahiptir. Bununla birlikte spor, sosyal açıdan kişisel ve toplumsal konumunu korumaya da devam etmektedir. Bu bağlamda çalışmada, Türkiye'de öne çıkan dört spor kulübünün finansal, sportif ve sosyal açılardan performanslarının incelenmesi ve sıralanması amaçlanmıştır. Ayrıca çalışmada, karar problemlerinin çözümünde kullanımı gittikçe artan bütünleşik/hibrit modellere yönelik farklı toplulaştırma tekniklerine yer verilmiştir. Spor kulüplerinin performansları açısından sıralanması için bütünleşik karar modeli oluşturulmuştur. Bu modelde, kriterlerin ağırlıklarının belirlenmesi için İkili Karşılaştırma Ağırlıklandırma Tekniği'nden yararlanılmıştır. Ağırlıklandırma işlemi sonucunda, finansal kriterlerden aktif kârlılık, sportif kriterlerden futbolda kazanılan kupa sayısı ve sosyal kriterlerden stadyum doluluğu, ana kriter gruplarında ilk sıraları almıştır. Karar probleminin çözümü için çok kriterli karar verme tekniklerinden SAW, TODIM, EDAS, VIKOR, QUALIFLEX ve MAPPAC kullanılmıştır. Söz konusu çözümlerin toplulaştırılmasında ise Borda, Copeland, Nanson, Ortalama, Cook ve Seiford, Kemeny toplulaştırma tekniklerinden yararlanılmıştır. Bütünleşik sıralamalarda, finansal performans açısından Beşiktaş ilk sırada bulunurken; sportif, sosyal ve genel performans sıralamalarında Galatasaray ilk sırada yer almıştır. Sonuç olarak spor kulüplerinin sürdürülebilir başarılar elde etmesi için finansal yapılarını düzeltmeleri, sosyal sorumluluk açısından ise toplumun geneliyle etkileşim içinde olmaları ve futbol dışında kalan takım sporları ve bireysel sporlara olanaklar yaratmaları gerekmektedir. Abstract The sports industry has a global scale that includes stakeholders such as sports clubs, fans, sports lovers, broadcasters, and financial investors. Besides, sports continue to maintain their socially personal and community position. In this study, financial, sportive, social, and general performances of four of the leading sports club in Turkey were examined and ranked in this regard. Also, different aggregation techniques for integrated / hybrid models, which are increasingly used in the solution of decision problems, were included in the study. An integrated decision model has been created to rank sports clubs in terms of performance. In this model, the Pairwise Comparison Weighting Technique was used to determine the weight of the criteria. As a result of the weighting process, return on assets ratio from financial criteria, the number of trophies won in football from sportive criteria, and the stadium occupancy from social criteria took the first place in the main criteria groups. SAW, TODIM, EDAS, VIKOR, QUALIFLEX, and MAPPAC, which are MCDM techniques, were used to solve the decision problem. Borda, Copeland, Nanson, Average, Cook and Seiford, Kemeny, aggregation techniques, were used to integrate these solutions. While Beşiktaş ranks first in terms of financial performance in integrated rankings, Galatasaray ranks first in sports, social, and general performance rankings. As a result, to achieve sustainable success, sports clubs need to improve their financial structure, in terms of social responsibility, they must interact with the general public and create opportunities for non-football team sports and individual sports. * Sorumlu yazar, Arş.
